MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters PatentNO. 703,825, dated July 1,1902.

Applicationfiled November 18, 1901. 7 Serial No. 82,752. (No model.)

To all whom, it may concern:

Be it known that we, JOHN QUIST and CHARLES QUIs'r, citizens of theUnited States, residing at Mystic, in the county of Appanoose and Stateof Iowa,have invented certain new and useful Improvements in MechanicalMovements; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertainsto make and use the same. I

This invention relates to a novel mechanical movement; and the object oftheinvention is to provide simple and improved mechanism applicable towashing-machines, churns, and to all other machines in which it isdesired to obtain an oscillatorymotion of one shaft or pivoted part fromarotating shaft whose axis is at right angles tothe axis of the shaft orpivoted part first mentioned. I

The invention is illustrated in the accompanyin gdrawin gs, in whichwehave shown it in connection with a washing-machine, and wherein Figure 1is a vertical sectional view of a washing-machine embodying theinvention. Fig. 2 is a topplan view of the gearing. Fig. 3 is an endelevation of the gearing, showing the yoke at right angles to therotating shaft.

Fig. 4 is a detail view of the yoke, and Fig. 5 is a detail view of thegrooved ball or head.

Referring now more particularly to the drawings, the numeral ldesignates a washing-machine of any approved construction, 2

3 5 its oscillatory shaft-carrying a rubber 3, and

4 an operating-shaft journaledlin a bearingbracket 5 and carrying a fly-.wheel 6 and crank-handle 7 whereby it may be operated.

The invention consists in means for transmitting oscillatory motion tothe shaft 2 from the continuously-rotating shaft 4, whose axis isarranged at right angles to said oscillatory shaft.

Fixed-1 to the upper end of the oscillatory shaft and journaled at 8 to.the bearingbracket to swing-in a horizontal plane is a yoke 9, carryinga swiveled shoe 10, which traverses a groove 11, formed in a ball orspherical head fixed to theinner end of the rotating shaft 4. Thisgroove is of a peculiar form, having substantially the shape of thefigure 8, and the shoe in traversing it is caused .to impart oscillatorymotion to the yoke and thence to the shaft 2.

In the operation of the device,when motion is imparted to the rotatingshaft, with the parts arranged as in Fig. 3, the shoe, which is locatedat the point of crossing of the two loop-shaped portions of the groove,is caused to first follow the cross of one of the said loop-shapedportions, whereby the yoke is swung in one direction of its oscillation,and then follow the cross of the other loopshaped portion of the groove,whereby the yoke is caused to swing in a direction reverse to thatpreviously described.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, andadvantages of the invention will be readily understood without a moreextended explanation.

Various changes in the form, proportion, and minor details ofconstruction may be made within the scope of the invention withoutdeparting from the spirit or sacrificing any of the advantages thereof.

As before stated, the invention is applicable to the shuttle motion ofsewing-machines, to churns, to washing-machines, and to all machines inwhich it is desired to obtain an oscillating motion of one shaft orpivoted part from a rotating shaft arranged at right angles thereto.Hence we do not limit the invention in application to a washing-machineor any other particular structure, but reserve the right to employ itwherever it may be found applicable.

Having thus described our invention, what we desire and claim by LettersPatent is- 9 1. A mechanical movement embodying an oscillatory shaft, arotating shaft, the axes of the shafts being'arranged at right angles toeach other, a swinging yoke connected to the oscillatory shaft, a ballor spherical head connected to the rotating shaft and having asubstantially 8-shap ed.groove,-and a shoe upon the yoketo traverse saidgroove, where by oscillatory motion is imparted to the said oscillatoryshaft and yoke, substantially as :00 described.

2. The combination with a suitable bearing, an oscillatory shaft, and arotating shaft journaled in said shaft being disposed at right angles toeach other, of a yoke fixed to the oscillating shaft and mounted toswing upon said bearing; a ball or spherical head carried by therotating shaft and having a substantially S-shaped groove, and aswiveled shoe upon the yoke traversing said groove, substantially asdescribed.

In testimony whereof we have hereunto set 10 our hands in presence oftwo subscribing witnesses.
